World-class code editing, debugging, performance tooling, a flexible build system, and an instant build/deploy system all allow you to focus on building unique and high quality apps.

Instant Run

Push code and resource changes to your app running on a device or emulator and see the changes instantly come to life. Instant Run dramatically speeds up your edit, build, and run cycles, keeping you "in the flow."

Intelligent code editor

Write better code, work faster, and be more productive with an intelligent code editor that helps you each step of the way. Android Studio is built on IntelliJ and is capable of advanced code completion, refactoring, and code analysis.

Fast and feature-rich emulator

Install and run your apps faster than with a physical device and test your app on virtually any Android device configuration: Android phones, Android tablets, Android Wear, and Android TV devices. The new Android Emulator 2.0 is faster than ever and allows you to dynamically resize the emulator and access a suite of sensor controls.
